The Quick Read: The best program for your situation is the one that pays off your first mortgage and deals with your second lien in the same transaction. A second mortgage never disappears on its own when the first is refinanced, so the new loan must pay it off, or the second lender must agree in writing to stay behind the new first. Short-term rental (STR) files add one more test: the lender must accept your hosting income as the rent that covers the payment.
- Leverage is capped by LTV (loan-to-value, the loan as a share of the property’s appraised value), and select wholesale-network programs set the ceiling for STR cash-out files.
- Expect a credit score of 640 or higher and about 12 months of hosting history.
- Coverage on a refinance typically starts at 1.00 on these programs, and the second lien counts in that math if it stays.
- Paying off the second reduces your net cash. Keeping it requires the junior lender’s consent.
Lendmire is a mortgage broker. It does not lend. It shops a network of wholesale DSCR lenders and matches the file to the program that fits. That matters here because no single program is “the best” when a second lien is in the picture. The right fit depends on how much equity you have, what the second mortgage is, and how your hosting income is documented. Lendmire arranges DSCR investor loans across 40 states plus Washington, D.C., which is 41 markets total.

This guide builds on the basics in Lendmire’s complete DSCR loans guide. Here the focus is narrow: one rental, two liens, and a cash-out goal.
Key Terms Defined
Cash-out refinance: A new loan that pays off the old one and gives you the leftover equity as cash.
DSCR (debt service coverage ratio): Monthly rental income divided by the full monthly housing obligation. That obligation is principal, interest, taxes, insurance, and any HOA dues, together called PITIA.
Second mortgage (junior lien): A loan secured by the same property that ranks behind the first mortgage if the property is ever sold to pay debts. A HELOC (home equity line of credit) is the most common type.
Subordination agreement: A signed, recorded document in which the second lender agrees to stay in second place behind a new first mortgage.
Combined leverage: The first mortgage plus the second lien, measured against the property’s appraised value.
Seasoning: The waiting period a lender wants between events, such as buying a property and refinancing it. About 6 months is the common expectation for cash-out files across most of the network.
Why a Second Mortgage Changes the Refinance
A refinance replaces your first mortgage. It does not touch the second. That is where the trouble starts.
Lien priority normally follows recording order. When the old first is paid off and released, the second lien moves up. Nolo explains that the second mortgage would become the first lien and the new mortgage would fall to second position. New first-lien lenders will not close in that spot. So the second lien has to be dealt with.
You have three options:
1. Pay it off from the new loan’s proceeds. The new loan covers both liens, and the second is released.
2. Pay it off separately. You use cash from another source and close it out.
3. Subordinate it. The second lender signs an agreement to stay behind the new first.
Option one is usually the cleanest. Once the second is retired, nothing needs to be subordinated, and the lien picture is simple. Options two and three exist for specific situations, and both add moving parts.
How Underwriting Treats the Second Lien, Step by Step
Here is how a lender in the network walks through the file, in order.
Step 1: Map every lien
The first job is a title search plus payoff statements for each lien. A payoff figure is not the balance on your last statement. It includes interest through the closing date plus fees. A HELOC that looks smaller on paper can pay off larger, and that shrinks your net cash.
Step 2: Classify the transaction
Paying off a second mortgage usually makes the refinance a cash-out loan, unless the line was originally used to buy the property. That classification matters because it decides which leverage cap applies to the file. Subject to lender guidelines, the exact limit moves with credit, coverage, and loan size. A second used to buy the property may be treated differently, depending on the program.
Step 3: Count combined leverage
Add the new first loan, any second that stays, and costs against the appraised value. If the second is paid off inside the new loan, the payoff is part of the new loan balance. Either way, the total has to fit under the cap.
Here is a worked example using placeholder inputs, not market data. Say a short-term rental appraises at $500,000. At 70% cash-out leverage, the new loan can reach 70% of that value. The existing first and second liens, plus closing costs, come out of that same 70% before you see any cash. The thinner your equity, the smaller the cash you can pull. If the two liens already eat nearly all of the 70%, there may be little or nothing left.
Step 4: Run the coverage test
DSCR is monthly rent divided by the full monthly housing obligation. If you pay off the second and roll it into the new first, you now have one larger payment instead of two. If the second stays, both payments count. A more aggressive cash-out raises the payment, which pulls the ratio down. On STR refinances, 1.00 is where many select programs start. Stronger ratios open better pricing and leverage.
Clearing 1.00 does not mean the property produces positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, platform fees, and capital expenses all sit outside the calculation. A short-term rental can clear the ratio and still be tight in a slow month.
Step 5: Establish the income figure
The appraiser’s standard rent schedule, Form 1007, documents monthly rent from comparable one-unit rentals. McKissock notes the form cannot be used to determine or document short-term rental rates. Multiplying a nightly rate by 30 is not a valid method either.
HousingWire reports that forcing STR income onto the 1007 often produces artificially low coverage ratios. Some programs use your trailing twelve months of actual booking income. Others use a projected-income analysis built from market data. Lenders in the network usually want about 12 months of hosting history on refinances, so actual records tend to drive the number.
Projections do not count in full. Lenders commonly apply expense factors or haircuts to gross short-term income before the DSCR math. Each program sets its own, which is one reason shopping the file across several lenders matters.
Step 6: Subordination, if the second stays
If you keep the second, the new lender sends a subordination request to the junior lender. Closing becomes conditional on the signed, recorded agreement. Subordination is voluntary. Lawyers.com notes that most lenders won’t refinance a first mortgage unless the second-mortgage lender signs one, and that second lenders do not always agree. Bills.com adds that many HELOC lenders look at a combined loan-to-value threshold before agreeing. A bigger cash-out leaves less cushion behind the new loan, so consent gets harder as leverage rises.
Pay Off the Second or Keep It?
Here is the decision in one table.
| Your situation | Typical path | Tradeoff |
|---|---|---|
| Ample equity, balance is modest | Pay off inside new loan | Lower net cash, simplest file |
| Thin equity near the 70% cap | Pay off inside new loan | Cash-out may shrink to little |
| Second has a very small balance | Pay off inside new loan | Often not worth a consent request |
| You want maximum cash and second lender is cooperative | Subordinate | Depends on junior lender’s consent |
| Second is a HELOC product not written for LLC borrowers | Payoff usually cleaner | Network programs can restrict such liens |
Keeping the second only makes sense when the junior lender will actually sign and the combined leverage still fits. Request that consent early, before you spend money on an appraisal.
Where the General Rule Breaks
A few situations catch investors off guard.
A zero-balance HELOC. The lien stays recorded until it is formally closed and released. A line you never use can still block a refinance until the lender files the release. Ask for a closure letter along with the payoff statement.
Home equity investment liens. These are typically junior as well. They usually need the investor’s consent to subordinate, and cash-out refinances may be restricted around them.
A second opened shortly before the refinance. If you open a line right before a planned refinance, you create a subordination request you did not need.
LLC-owned rentals. Many investors hold STRs in an LLC. A second lien already sitting on an LLC-owned rental is a flag, because some investment HELOC products are not written to LLCs. LLC-titled borrowers are reviewed per lender program requirements, so confirm eligibility early.
A first note that restricts additional liens. Some existing first-mortgage notes limit adding liens. Read yours before you plan any structure that leaves multiple loans in place.
A second used to buy the property. If a piggyback second was part of the original purchase, its payoff may be treated differently than a later draw. Lenders look at how the line was used.
Local rules. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, regardless of income.
Appraisal forms may also change over time, but the underlying problem stays: monthly rent comps do not capture nightly-booking income.
What Programs in the Network Look For
Across a wholesale network, STR cash-out programs share a rough shape. On the strongest files:
- Cash-out LTV tops out at about 70% on short-term-rental collateral, and purchase loans can go higher, so keep the two loan types separate when you compare programs.
- Credit scores start at 640 on STR programs, though stronger scores open better leverage.
- A hosting history of about 12 months is the usual expectation.
- Coverage typically starts at 1.00 on refinances. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
- Loan sizes run up to $3,000,000 on standard programs. Above $2,500,000, the network generally holds to 30-year fixed structures.
- Reserves vary by lender, leverage, and loan size. About 6 months of PITIA is common, and larger loans typically step up.
The spine of the lineup is the 30-year fixed. Extended terms and interest-only periods are available through select lenders, and ARM structures exist for investors who want them.
A larger equity cushion lowers the payment and can lift the ratio. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear two tests at once: enough equity and enough rental coverage.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, seasoning, and reserves still apply.
Pre-Application Checklist
Gather these before you ask for a quote:
- Payoff statements for the first and second liens.
- A closure or freeze letter for any HELOC you want shut.
- Platform records covering your hosting history, such as booking statements.
- Proof of insurance and current hazard coverage on the STR.
- Entity documents, if the property sits in an LLC.
- Reserve statements showing available funds.
When This Is the Wrong Move
Sometimes a cash-out refinance on an STR with a second lien is not the right call.
- Equity is too thin. If the two liens already consume most of the 70% cap, the cash left over may not justify the cost.
- Hosting history is short. Under about 12 months, a refinance may not fit. Waiting can open more programs.
- Coverage is under 1.00 and leverage is already high. Sub-1.00 programs are available through select lenders in the network, with leverage and terms adjusted, but that stacks more pressure on a tight file.
- Cash-out is not the real goal. If you only need to lower the payment on one loan, a refinance that adds a new lien event may not be worth it.
Each cash-out is its own credit event and lien event. That matters if you plan to pull equity from several rentals.
Finding the Best Program for Your Situation
No ranked list answers this question honestly. The right program depends on your equity, your credit tier, your income documentation, and what your second lien is. That is why a broker that sees many guidelines at once can narrow the field faster than a single lender’s page. Lendmire’s role is to match your scenario to the program whose overlays fit it.

Frequently Asked Questions
Do I have to pay off my second mortgage to refinance my short-term rental?
No, but the second lender must agree in writing to stay behind the new first mortgage. Without that signed, recorded subordination, the second would move into first position, and most lenders will not close that way. Paying it off inside the new loan avoids the question entirely.
Is paying off a second lien treated as cash-out?
Usually, yes. Retiring a non-purchase-money second typically classifies the refinance as cash-out. On short-term-rental collateral, cash-out typically tops out around 70% LTV.
Can a lender use my Airbnb income for the DSCR calculation?
Often yes, but not through the standard rent schedule. McKissock says Form 1007 cannot document short-term rates. Programs typically rely on about 12 months of actual booking history or a projected-income analysis, with expense factors applied, subject to lender guidelines.
Does a HELOC with a zero balance still matter?
Yes. The lien remains recorded until it is formally closed and released. Ask your HELOC lender for a closure letter so title shows it cleared before the refinance.
What if my second lender refuses to subordinate?
Then paying it off from the new loan’s proceeds, or from separate funds, is the path. Subordination is voluntary, and refusals happen more often as combined leverage climbs. Asking early keeps you from spending on an appraisal that cannot lead to a closing.
